How old do you have to be to get contacts and/or get laser eye surgery?

I'm 14 and I'm trying to get contacts the school year starts. My glasses get in the way. Kids that were in my classes have had contacts and they were only 12/13 at the time.
And if i'm able to get contacts would I be allowed to pick the color I want? cause I have a stigmatism in both eyes.
And if contacts cant fix my stigmatism could I get laser surgery at this age?
